Questions & Answers for Nikon Inc. SD-9 High Performance Battery Pack

Batteries in or out?

Do I remove the 4 x AA batteries from the SB-900 before I attach this, or do they stay in the flash while its in use?

No, the 4 in the flash itself are always needed, regardless of external power

Question

What is the sequence for battery use when there are 4 batteries in the SB900 and 8 in the SD-9?

Will the 8 batteries in the SD-9 get used first and then the 4 in the SB-900, or are all 12 batteries drained equally. I ask because I want to know what the overall effect is when I put 8 new batteries into the SD-9, but leave the 4 in the SB-900 unchanged.

I believe the batteries in the SD9 are only powering the flash capacitor while the four int the speed light are only powering the on board computer. As long as its attached, the batteries in the pack will drain first under heavy use.

They are use equally. The use of the external power source provides a stable power supply, increases the number of flash firing and shortens recycling time.

Does this SD-9 battery pack help the sb900 not overheat as quickly?

No it actually makes it worst. I got 2 units last week to use for an event and my assistent had to switch between speed lights as they were overheating much faster then they normally did the past, some times the speed light would stop working after 4 shots!So if anything they made my life worst and now I need to find someone to buy them off me since all they do as add dead wight.

The lights on my sd-9 don't flash when I install new batteries. What's up?

How do I know if the sd-9 is working if it doesn't flash or flicker

Each of two ready-lights (A and B) lights up for each circuit.

• When the SB-900’s power is on, the SD-9 starts to charge the power in sync with the SB-900, and the ready-light lights up in red. The ready-light goes off when the power charge is completed.

• The ready-light blinks in red when there is danger of the SD-9 overheating because of its repeating flash operation (power charge does not start). It stops blinking when the SD-9 is cooled down to normal temperature (power charge is available).
